Oh god, save us all from the powerfully held beliefs of Health Psychologists! Especially those at the lower end of the quality spectrum, whose wild musings can flourish, unchecked by strong research standards.

They think this is all good (hey, if its in your head, you can talk about it and get better, right?). They don't realise the harm they do if the conclusions they draw are incorrect.

So because adrenaline (and a few other chemicals) affect the stomach the ignore your problems therapy will solve IBD [facepalm]
This is bad science, it would be akin to saying CBT will cure the common cold and the flu, the success rate will be almost 100%, and they can write editorials about their miracle cure. They better hope that one is not double blind tested

CBT for IBD may have some peripheral effects (and spontaneous remission), which i am sure will be considered way out of context as a "cure"
